Example of our stylized scattering. Left: physically correct single scattering using the original occluders. The leaves of the tree block most of the light, causing a rather subtle effect. Right: stylized scattering with occluder manipulation. Using our system, an artist can easily add holes into the shadow map of the tree, producing more pronounced scattering effects. While physically incorrect, it is not obvious for the viewer that the right image uses fake occlusion information. Surface shadows are created from the original shadow map.

The 95% confidence interval highlighted in green for the t-distribution with 4 degrees of freedom (N = 5, N = 3 and α = 0.05). The left most image shows the two-sided confidence interval, while the middle and right image show the one-sided confidence intervals. The areas highlighted in red fall outside the interval.

We compare our method to conventional and gradient-domain path tracing in an equal-time comparison. Gradient-domain path reusing produces visually pleasant images with much less noise than path tracing and significantly lower artifacts than gradient-domain path tracing given the same time.
